Some examples: For comparison, when I boot v4.17 it looks like this: | Linux version 4.17.0 (morse@melchizedek) (gcc version 4.9.3 20141031 | (prerelease) (Linaro GCC 2014.11)) #9886 SMP PREEMPT Thu Jun 21 10:30:55 BST | 2018 If I apply some extra patches and make some uncommitted changes, it looks like this: | Linux version 4.17.0-00025-ga22ca2234824-dirty (morse@melchizedek) (gcc | version 4.9.3 20141031 (prerelease) (Linaro GCC 2014.11)) #9887 SMP PREEMPT | Thu Jun 21 10:46:22 BST 2018 Hence we read your '4.17.0-45864-g29dcea8-dirty' line as v4.17 with extra patches and uncommited changes, and similar with this v4.18-rc2. I agree 7daf201 is the head commit for v4.18-rc2, but something has gone wrong here. Could you try building from a fresh clone of Linus' tree? (I suspect at some point you've applied a patch, and have then been merging upstream, instead of 'fast forwarding') Thanks, James
